Abstract: The present disclosure provides processes for the production of substituted phenylene aromatic diesters and the resultant compositions. The processes include reacting an aromatic diol with an aromatic carboxylic acid or a derivative thereof. The aromatic diol and/or the aromatic carboxylic acid (or derivative thereof) is/are substituted. The reaction forms a substituted phenylene aromatic diester with the structure (II): wherein R1-R14 are the same or different. At least one of R1-R14 is selected from a substituted hydrocarbyl group having 1 to 20 carbon atoms, an unsubstituted hydrocarbyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a heteroatom, and combinations thereof.
